Centrifugal pump and movable platform

The invention provides a centrifugal pump and a movable platform with the same. The centrifugal pump is provided with a transition cavity and a working cavity, a fluid medium flowing in from an inlet of the centrifugal pump sequentially passes through the transition cavity and the working cavity and flows out from an outlet of the centrifugal pump, the centrifugal pump comprises an impeller, the impeller is provided with blades, and the blades are arranged in the working cavity. The fluid medium needs to firstly flow into the transition cavity and then flow into the working cavity where the blades are located, which means that the output flow of the centrifugal pump can be controlled by controlling the flow of the fluid medium flowing into the working cavity from the transition cavity. When a fluid medium with pressure flows in, the fluid medium can be output at a lower flow rate by reducing the flow rate of the fluid medium flowing into the working chamber from the transition chamber.
